Use the info from the az123 site and do some changes. Cut a circle of aluminum to replace the reflector and mount the LS/o on it with some thermal paste. Run a wire from positive contact on the LS to the postive contact on the flashlight. Do the same for the neg. Use a 3 cell M*g. This will be very bright.
I left out some details but this is the general way to get a bright light.
